Abstract (en)

[origin: US2016134866A1] A user equipment includes a transceiver and a decoder. The transceiver is configured to receive an encoded bitstream of video. The decoder includes processing circuitry. The decoder is configured to identify a first intra mode associated with a top prediction unit (PU) in relation to a current PU of the encoded bitstream of video. The decoder is also configured to identify a second intra mode associated with a left PU in relation to the current PU. The decoder is also configured to determine a plurality of most probable modes (MPMs) based on the first intra mode and the second intra mode, wherein a number of modes is greater than thirty-five.
